This tubing string of the present embodiment is tested in accordance with the following steps:
Step one, running string: will enter in horizontal well under staged fracturing horizontal well produced fluid cross section tubing string, make the moisture tester 4 of guiding plug 1, tail pipe 2, eye pipe 3, flow, packer 6, be all positioned at the horizontal segment of horizontal well, now, packer 6 is positioned at test section bottom.Have three perforated intervals with reference in Fig. 1, figure, the perforated interval of rightmost is the perforated interval of bottom, and now, packer 6 is positioned at the right side of the test section of rightmost.
Step 2, production profile: promote tubing string, packer 6 is made to rise to above the perforated interval of bottom, namely packer 6 is made to be arranged in the middle of two, the right side perforated interval of Fig. 1, then deep water swab 9 is utilized to carry out swabbing operation, now, through the moisture tester 4 of inflow-rate of water turbine be all by the fluid of that perforated interval of the rightmost side.Promote tubing string gradually subsequently, packer 6 is made to pass through different perforated interval one by one, form the combination of different perforated interval, the moisture tester 4 of downhole flow continues metering various combination interval production fluid situation, such as promote a perforated interval on the basis of the above again, make packer 6 between the perforated interval of two, left side, then now moisture tester 4 metering of downhole flow is two, the right perforated intervals combination production fluid situations; When packer 6 is positioned at the left side of the perforated interval of the leftmost side time, then what the moisture tester 4 of downhole flow measured is three perforated interval combination production fluid situations.
Step 3, trips out test string: upper lifting pipe post, trips out test string.
Step 4, playback of data: take off the moisture tester 4 of flow, playback of data, contrast test plate draws Liquid output and the water content of various combination interval.Test plate is herein the curve map that the data recorded in each production fluid section in the well with known Liquid output carry out being combined to form.
Through contrast and analysis, the production fluid situation of each perforated interval in testing well section can be extrapolated.
Embodiment 2:
On the basis of embodiment 1, the present embodiment improves further, and as shown in Figure 1, oil pipe pipe string is also serially connected with downhole on-off actuator 5 and Second Sight pipe 7, described downhole on-off actuator 5 is positioned at below packer 6, and described Second Sight pipe 7 is positioned at the top of packer 6.
A method of testing for staged fracturing horizontal well produced fluid cross section tubing string, comprises the steps:
Step one, running string: will enter in horizontal well under staged fracturing horizontal well produced fluid cross section tubing string, make guiding plug 1, tail pipe 2, eye pipe 3, the moisture tester 4 of flow, derailing switch 5, packer 6, Second Sight pipe 7 is all positioned at the horizontal segment of horizontal well, now, derailing switch 5 is in open mode, packer 6 is entered under convenient, make, initial liquid outlet quantity flows away by derailing switch 5, packer 6 is finally made to be positioned at test section bottom, with reference to Fig. 1, three perforated intervals are had in figure, the perforated interval of rightmost is the perforated interval of bottom, now, packer 6 is positioned at the right side of the test section of rightmost.
Step 2, production profile: after derailing switch 5 cuts out, promote tubing string (in order to upwards promote packer 6 smoothly, be provided with Second Sight pipe 7, the fluid of the perforated interval above packer 6 is up flowed out by Second Sight pipe 7, the lifting of packer 6 can not be hindered) make packer 6 rise to above the perforated interval of bottom, namely packer 6 is made to be arranged in the middle of two, the right side perforated interval of Fig. 1, then deep water swab 9 is utilized to carry out swabbing operation, now, the fluid of the perforated interval of the rightmost side all enters tubing string by eye pipe 3, upwards extracted by deep water swab 9 after the moisture tester 4 of inflow-rate of water turbine again, all by the fluid of that perforated interval of the rightmost side through the moisture tester 4 of inflow-rate of water turbine.Promote tubing string gradually subsequently, packer 6 is made to pass through different perforated interval one by one, form the combination of different perforated interval, the moisture tester 4 of downhole flow continues metering various combination interval production fluid situation, such as promote a perforated interval on the basis of the above again, make packer 6 between the perforated interval of two, left side, then now moisture tester 4 metering of downhole flow is two, the right perforated intervals combination production fluid situations; When packer 6 is positioned at the left side of the perforated interval of the leftmost side time, then what the moisture tester 4 of downhole flow measured is three perforated interval combination production fluid situations.
